EOS 60D Firmware Version 1.0.4 resolves the following issues, which may occur in the RAW mode depending on shutter release timing: Thumbnail is black. Data is not written to CF card (or microdrive). Only the thumbnail image is affected, there is no problem with the main image. With EOS 60D cameras that have Firmware Version 1.0.0, 1.0.1 or 1.0.2 installed, in cases where data stored in the camera's buffer memory has not yet been written to the CF card or microdrive, that data will be written when the menu button is pressed, or when the shutter button is pressed halfway. Version 1.0.4 can be used to update EOS 60D cameras with version(s) 1.0.0, 1.0.1 or 1.0.2.
